KNOW YOUR LEVEL
01

Find Out if You’re Getting Enough

Sun exposure, diet, and supplements don’t tell you how much vitamin D your body actually has available. Testing gives you a clear baseline and shows whether your current routine is moving your level in the right direction.

Catch Problems Before They Affect Your Strength

Vitamin D helps your body absorb calcium and maintain healthy bones. Looking at vitamin D alongside alkaline phosphatase (ALP) can provide added context about bone turnover—especially when a deficiency is significant or prolonged.

Low Testosterone and Poor Sleep

Vitamin D does more than support strong bones, healthy muscles, and normal immune function. It may also play a role in testosterone, sleep, and mood. Blood testing shows where your level stands and whether it may be connected to how you feel and perform.

CHECK KIDNEY FUNCTION

Make Sure Your Body Can Activate It

Your kidneys help convert vitamin D into a form your body can use. Creatinine and eGFR help show whether kidney function could be affecting vitamin D and mineral metabolism.

Reviews from Rythm customers that have seen health improvements in less than 90 days.

The blood draw was easy to do!

The blood draw was easy to do and follow instructions. Pick up and shipping was easy with FedEx. The text messages throughout the whole process were helpful and easy to follow. The only thing that I would like to see is more testing. I would like to see where the rest of my vitamin levels are.

So pleased with Rhythm!

I have been doing Rhythm tests for 6 months now. This month I am feeling great! I followed my recommendations that came with my results and it has helped my health improve. I like how the results are explained thoroughly and easy to understand with recommendations to improve it next month. I had no idea that my low vitamin D can affect so many things! I really feel so much better all over and I have Rhythm to thank for that! I like participating and taking control of my health. Your health is your wealth!

One of the best decisions you can make

I’ve been using Rythm Health since August 2025 for monthly at-home blood work, and it’s honestly been a game changer for me. Having the kits show up at my door each month makes everything so much simpler — no scheduling appointments, no waiting around, just quick and easy testing on my own time. Since doing this consistently, I’ve been able to get my levels stabilized and really dial in my health. I even built a vitamin regimen based on the results, which has helped more than I expected. Another thing I love are the perks they offer — legit discounts with reputable companies I actually use. It’s one of those things you don’t think about at first, but it ends up adding a ton of value. And if you ever need deeper or more advanced labs done, they’re partnered with companies that make that process super straightforward too. Overall, Rythm Health has made staying on top of my fitness and wellbeing way easier. Highly recommend to anyone wanting better control over their health without the usual hassle.

So pleased with Rhythm!

I have been doing Rhythm tests for 6 months now. This month I am feeling great! I followed my recommendations that came with my results and it has helped my health improve. I like how the results are explained thoroughly and easy to understand with recommendations to improve it next month. I had no idea that my low vitamin D can affect so many things! I really feel so much better all over and I have Rhythm to thank for that! I like participating and taking control of my health. Your health is your wealth!

One of the best decisions you can make

I’ve been using Rythm Health since August 2025 for monthly at-home blood work, and it’s honestly been a game changer for me. Having the kits show up at my door each month makes everything so much simpler — no scheduling appointments, no waiting around, just quick and easy testing on my own time. Since doing this consistently, I’ve been able to get my levels stabilized and really dial in my health. I even built a vitamin regimen based on the results, which has helped more than I expected. Another thing I love are the perks they offer — legit discounts with reputable companies I actually use. It’s one of those things you don’t think about at first, but it ends up adding a ton of value. And if you ever need deeper or more advanced labs done, they’re partnered with companies that make that process super straightforward too. Overall, Rythm Health has made staying on top of my fitness and wellbeing way easier. Highly recommend to anyone wanting better control over their health without the usual hassle.

What our customers tracking their vitamin D levels are saying

Reviews from Rythm customers that have seen health improvements in less than 90 days.

The blood draw was easy to do!

The blood draw was easy to do and follow instructions. Pick up and shipping was easy with FedEx. The text messages throughout the whole process were helpful and easy to follow. The only thing that I would like to see is more testing. I would like to see where the rest of my vitamin levels are.

Frequently Asked Questions

How is Rythm different?

Most blood testing companies charge $500 or more for a single test per biomarker, providing only a one-time snapshot that doesn’t capture your long-term health trends or reflect your true baseline. This approach can lead to missed patterns or even misdiagnoses due to limited data. Rythm takes a different approach, using monthly tracking to build a detailed picture of your health over time. This allows for more accurate insights, better optimization, and a clearer understanding of how your body is evolving.

Rythm provides actionable suggestions and tips to help you optimize each biomarker

Is Rythm HIPAA compliant?

Yes, Rythm is HIPAA compliant. Your data is securely stored and handled in accordance with strict privacy and security standards.

Can I cancel anytime without fees?

Does Rythm accept HSA/FSA payments?

Yes, Rythm is HSA/FSA eligible. You can use your HSA or FSA card at checkout or submit your Rythm receipt to your provider for reimbursement.

You will receive your results within 3 business days – as long as it's returned within 7 days of receiving your kit. Delays can occur if you do not send your sample back in time.
